MACHINE FOR MANUFACTURING BRUSHES.

To @ZZ whom t may concern,.-

the construction of the bristles feeding, sepaa rating, and bunching mechanlsm of a machine,

of this nature, whereby the machine can be operated rapidly and eflciently and will have long life.

The machine which is illustrated as embodyn ing the invention has a channel through which the mass of bristles are fed and from which the bunches are successively separated, compacted, and lifted into the grasp 0f thumbs y and lingers which carry them to the plunger,

which applies a staple cut from a continuous -f length of wire to the middle ofthe bunch,

Cthen drives the staple and the middle of the bunch into a socket'in the body of the brush that is laid upon the table beneath the plunger. v

Figure 1 of the accompanying drawings shows a side elevation of the machine. Fig. 2 shows a horizontal section 0n the plane 2 2 of Fig. 1. Fig. 3 shows the separator and packer about to separate bristles from the end of the mass inthe channel. Fig. A shows the separator and packer in the positions 0ccupied after they have effected' a separation of some of the bristles from the mass in the channel. Fig. 5 shows the position of the parts after the bristles which are to form a order to permit the plunger to drive the mid dle of the bristles and the staple into a socket in the body of a brush. Fig. 9 shows an end view of the bristle-gathering part of the machine.

` The bristles are placed i-n a horizontal channel formed between plates 1 and 2, that are `fastened to the frame in any desired manner. These bristles, which may be of any material, are advanced to the forward end of the 'channel by the pressure of a follower 3,'Wliich is drawn forwardly by a cord 4L and weight 5.

Supported above and movable vertically across the forward end of the bristle-channel are separating-plates 6, Figs. l and 2. The lower ends of these plates have straight front edges and curved rear edges, and they also on their front edges have hooked lugs 7, Figs. 3 kand 4. These plates are reciprocated vertically by a properly-timed cam 8 on the shaft 9, which has a driving-pulley 10, Fig. 1.

Supported below and movable vertically across the forward end of the bristle-channel` is a packing-plate 11which is drawn down by the lever 12, link 13, and cam 14 and is pushed up bythe lever 12 and spring 16, Fig. l. The upper end of this packing-plate has a sharp edge and is arranged to move across the forward end of the bristle-channel into and out of the space between the wall 16 in front of the end ofthe bristle-channel and the straight front edgesv of the separating-plates, Figs. 3, 4:, 5, and 6.

The Vweighted follower forces the bristles forwardly against the wall at the end ,0f the bristle-channel. At the proper time the separating-plates, which are abovel the channel,-

descendand separate `a quantity of bristles from the end of the mass in the channel, and simultaneously the packing-plate, which is below the bristles, rises and packs the separated bristles beneath the hooked lugs between the separating-plates and the front wall, Figs.v 3 .and 4.

Located in a guideway on the upper face of the top channel-plate is a horizontal liftingl blade 17. A crank-rod 18 connects this blade with a crank 19 on a horizontal shaft 20, that by means of the pairs of beveled gears 21 and 22 is drivenfrom the driving-shaft, Figs. 1 and 2. The forward end of this blade has a separating-point and an inclined edge. After the bristles have been separated by the downward movement of the separating-plates and compacted by the upward movement of the packing-plate, Fig. 11, the liftingblade is thrust forwardly, so that the point will separate and the inclined edge will lift just the desired quantity of bristles to form the required tuft. As this takes place the separating-plates are raised and the packing-plate is lowered, Fig. 5.

Movable in the guideway above the liftingblade is a carrier 23, that is connected by a crank-rod 211 with a crank 25 on the horizontal shaft, Figs. 1 and 2. The forward end of this carrier is provided with thumbs 26. Mounted on the carrier are a pair plates 27. The forward ends of these plates are provided with downwardly-pointing fingers 28. These fingerplates are connected by springs 29 with the carrier, Figs. 1 and 2. The studs 30 on the fingerplates to which the springs are connected are arranged to-engage with a pin 81, held by lugs on the guide-frame to limit the backward movement of the fingers, Figs. 1 and 2. /Vhen the bristles are raised by the lifting-blade, they are carried up back of the lingers 28 and then the carrier is advanced, so that the thumbs 26 pass beneath and hold up the bristles. As the carrier is moved forwardly the springs 29 hold the lingers back, so that the bristles are grasped between the fingers on the fingerplates and the thumbs on the carrier. When the bristles are held in this manner, the separating-plates are raised farther and the liftingblade is drawn back, Fig. 6. Then the carrier is moved forwardly and carries the bristles held by the thumbs and lingers beneath the staple-plunger 82, Figs. 7 and 8.

The wire 33, from which the staples are formed, is fed into the head 34 by horizontal rolls 35 on the vertical shafts 36, that are driven by beveled gears 87 from the drivingshaft, Figs. 1 and 2. The head 34 and the wire-cutter and staple-plunger supported by the head and the means for operating these mechanisms are of common construction and arrangement and may be substantially the same as those which are shown and described in United States Patent No. 330,688, November 17, 1885. Therefore a detailed description of these parts is not given.

After the bunch of bristles for the tuft has been carried by the thumbs and lingers into line with the staple plunger the plunger closes a staple 38 about the middle of the bristles, Fig. 8. At the same time the carrier is drawn back, so as to withdraw the thumbs from beneath the bristles in order that the plunger may carry the middle downwardly and drive the staple into a socket in the body of a brush which has been laid on the table 39, Fig. 1. Latches 40 are arranged on the carrier so as to engage with the rear ends of the linger-plates and hold the lingers against movement until after the thumbs have been withdrawn from beneath the bristles and the plunger has driver. the bristles downwardly. When the carrier-slide has been drawn back some distance, wedges L11, near its rear cnd,engage lugs 42 and lift the latches from the rear ends of the linger-plates and allow the lingers to be drawn backwardly by the springs until the spring-studs engage the stop-pin.

In this machine the bristles areseparatcd, compacted, lifted, and carried forwardly by light slides which have simple rectilinear movements that can be conveniently adjusted so that they will operate accurately and that can be so mounted that there is but little wear.
